4. Monitor the Excitation Radiation
Place a paper strip at the excitation beam exit of the sample
chamber as shown in Figure 19 and observe the condition of
excitation beam. Using the three position adjusting screws
mentioned before, adjust so that the excitation beam
(rainbow color) becomes brightest. You may need to
readjust all screws three or four times before obtaining the
most intense light amount.
NOTE:
Allow the lamp to stabilize for approximately 15 minutes after it
has been turned on, before optimizing the position.
